9DMV0431AKILFT

Overview

The 9DMV0431AKILFT is a PCIe clock multiplexer manufactured by Renesas Electronics. It operates with a 1.8 V supply voltage and supports frequencies from 1 MHz to 200 MHz. The device features two HCSL differential inputs and four LP-HCSL differential outputs. It includes integrated output terminations for direct connection to 100 Ω transmission lines, eliminating the need for external resistors. The component provides selectable asynchronous or glitch-free switching modes and is housed in a space-saving 24-VFQFPN package.

Feature Summary

• Supports PCIe Gen1-Gen3 Common Clocked (CC), Separate Reference no Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures
• Integrates 100 Ω output termination resistors, saving board space and components
• Selectable asynchronous or glitch-free switching modes for flexible system control
• Compatible with spread spectrum input signals for EMI reduction

Applications

• PCI Express (PCIe) Gen1/Gen2/Gen3 clock distribution systems
• Server and storage backplane designs requiring low-power clock muxing
• Industrial equipment utilizing PCIe interconnects

Part Context

This component belongs to the IDT SOC-Friendly Very-Low-Power (VLP) PCIe family, now part of Renesas Electronics following acquisition. The 9DMV04xx series is designed for system-on-chip applications requiring minimal power consumption and reduced bill-of-materials through integrated termination.
